Dutch Connection has run his last race of the season and will reappear in a 2000 Guineas trial next spring.
Trained by Charlie Hills to win the Acomb Stakes at York's Ebor meeting, he finished third behind the Aidan O'Brien-trained Gleneagles in the National Stakes at the Curragh on Sunday.
"He travelled really well but was then just found for a turn of foot," said Hills on his website, www.charleshills.com.
"However, he was staying on again at the end of the race and looks like he needs a mile now.
"He wasn't beaten far by a highly regarded horse, and we'll put him away for the year and aim at a Guineas trial in the spring.
"He was very much the biggest horse in the paddock and has the size and scope to improve considerably over the winter."
Hills also had news of a couple of other smart juveniles from his yard, Dancetrack and Aces, who ran a big race in the Champagne Stakes.
"Dancetrack got us off the mark for the week when winning easily in a good time at Leicester. There's plenty more to come from him and he could be one for the Somerville Tattersall Stakes at Newmarket," said Hills.
"Aces ran a cracker in the Champagne Stakes where his inexperience caught him out, however he wasn't beaten far by some very well regarded horses. He's another with a great temperament and all things being equal will be aimed at the Horris Hill."
